Isn't it well known that Apple is working on a car?

Is it? It is well known that they are hiring bunch of engineers with automotive industry backgrounds and are working on something related to cars. However I've also heard from friends in the industry that they're not really hiring people with backgrounds related to building actual car chassis.

I think the jury is still out on whether there will actually be an Apple car (as opposed to an Apple (co-)branded car full of Apple tech).
